2. Estimating krill recruitment and its variabiliity

   Abstract:  A maximum likelihood method is developed for the decomposition of krill density at length data into the proportion of recruits in population sampled in a net haul survey. Preliminary results from a series of 5 net haul surveys in the South Atlantic and the Indian Ocean sectors of the

3. Modelling krill recruitment

   Abstract:  A method is developed for using observed values of the mean proportion of recruits and its variance to model recruitment in a krill population in terms of numbers of recruits. The method includes the calculation of natural mortality and other parameters consistent with the observed

4. Preliminary model of krill fishery behaviour in Subarea 48.1

   Abstract:  A simple deterministic model is described which models the behaviour of the krill fishery in Subarea 48.1 and estimates the effort applied and the catch of krill in fine-scale squares. Parameters for the model are calculated from data reported to CCAMLR by Chile over the period 1989 to

5. Trophic ecology of demersal fish communities in waters to the south of Elephant Island, north of Livingston Island, north of Antarctic Peninsula and east of Smith Island, with note on the ecological role of the krill

6. A review on the feeding conditions of the baleen whales in the Southern Ocean

   Abstract:  Food habits of the southern baleen whales were reviewed being based on the published and unpublished data since 1946. Past geographical distributions of the krill in the whales stomach revealed that the frequency occurrence by krill size showed that the large krill(>50mm) occurs more

7. Distribution of salps near the South Shetland Islands; their ecological significance in the area

   Abstract:  Distribution and abundance of salps were studied near the South Shetland Islands during summer 1990/1991. Total salp biomass ranged between 0.1 and 2021.3 mg WW∙m-3 and was nearly equal to krill biomass in the area. Two species; Salpa thompsoni and Ihlea racovitzai were found, and the

8. Comparison of the distribution of particulate matters and the composition of particulate organic matter in suface waters between the coastal and oceanic areas off the northern South Shetland Islands in summer

   Abstract:  Biogenic silica (BSi), lithogenic silica (LSi), particulate organic carbon (POC) and nitrogen (PON), and chlorophyll a (Chl a) were measured in the surface waters (Author(s):  A. Shiomoto and H. Ishii (Japan) Title:  Comparison of the distribution of particulate matters and the

9. Some idea of numerical model for assessment of Euphausia superba biomass

   Abstract:  A numerical model is being developed for assessment of Euphausia superba in Antarctic Ocean, which consists of: (1)calculation of three dimensional current field using CCSR version (developed by Dr. Yamanaka of Center of Climate System Research, University of Tokyo) of the three

10. Report of an examination of the acoustic data from RV Eduardo L. Holmberg collected during the FIBEX study

    Abstract:  Data from the Eduardo L Holmberg FIBEX survey have been re-examined for incorporation into the BIOMASS Database in the approved standardised format. The results indicate the krill were concentrated to the western end of the South Orkney Islands. Density values are consistent with those
